SAFETY-ENVELOP.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed July 28, 1906. Serial No. 328,191.

To all whom it may concern.

Be it known that I, HENRY GEORGE TAY- LOR, a subject of the King of Great Britain, residing at Milton, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Safety-Envelops, of which the following is a specification.

The invention relates to an improvement in safety envelo s constructed of a single blank arranged or folding in a manner to reinforce all edges thereof.

One object of the invention is the provision of an integral address tag so arranged as to attach it for projection beyond the envelop l proper to provide for stamp cancellation or other official stamping without liability of injury to the envelop or its contents.

Another object of the invention is the use of a blank made up of connected sheets of paper and a textile fabric secured together, the blank being arranged for folding to dispose the fabric as a lining for the envelop, whereby to materially aid in protecting the contents.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view of the completed envelop With the address flap turned down in normal position, Fig. 2 is a similar view showing the flap extended for stamping purposes, Fig. 3 is a similar view with the envelop shown in folded condition ready to receive the con- 3 tents, Fig. 4 is a plan of the blank, the lines of fold utilized in forming the envelop being shown in dotted lines, Fig. 5 is an enlarged section of the completed envelop taken on a line 55 of Fig. 1, Fig. 6 is an enlarged sectional view on the line 66 of Fig. 2.

Referring particularly to the drawings, wherein similar reference numerals indicate like parts throughout the several views, my improved envelop is constructed'of a single blank 1 made up of duplicate sheets of paper 2 and a textile fabric 3, as canvas or the like. The fabric layer 3 is designed to reinforce the paper layer and aid in preventing destruction of the envelop by use, as by this arrangement the wearing or breakage of the paper layer will not expose or provide access to the contents of the envelop. The blank, which as will be understood, is formed to provide a face section 4, and side flaps 5 projecting from the respective side edges of the face section. The face section is extended beyond the upper edges of the side flaps to provide an address tag or flap 6.

To provide for the proper folding of the blank, the same is creased along certain lines, as the lines 7- 7 at the junction of the face section with the side flaps, the line 8-8 at the junction of the face section and address flap In addition to these lines of folding the blank is creased transverse its length on lines 99 and 10-10, extending in parallel relation to each other and to the upper edge of the blank, and spaced in approximate uniformity from the creasing line 88 and from each other. Adjacent the lower edge the blank is formed with an additional creasing line 11-11 extending transverse the length of the blank and parallel to the creasing lines 9 and 10, the line 1111 being preferably arranged such a distance from the lower edge of the blank as will provide the desired width of material to form a sealing flap, as will be hereinafter de scribed. Each of the side flaps 5 is further creased along the lines 12*12 and 1313, extending in parallel relation to each other and to the line of juncture or creasing 7 between the side flap and face section.

'As the blank is adapted to be folded along the respective lines engaged, as will presently appear, the face section of the envelop is that portion of the blank included between the lines 77 and the lines 10 and 11, while the side flaps proper constitute that portion of the blank included between the ines 10 and 11 and the lines 12 and the edge of the blank, the remainder of the blank being utilized as a reinforce for the edges of the completed article. The section of the blank between the folding line 1111 and the lower edge of the blank is adapted in the completed article to provide a bottom sealing flap, and in order to arrange for the more effective securing of this flap I prefer that the sections 14 thereof in alinement with the v side flaps be of somewhat less length thanthe portion 15 of the face section. The sections 14, however, 'of the side flaps are provided With extensions 16 of relatively nar row width and equal in length to the excess length of the portion 15 of the sealing flap, said extensions being arranged about midway the width of the respective side flaps, or in alinement with the folding lines 12 of each of the said flaps, as clearly shown in Fig. 4.

V That portion of the blank included befastener.

tween the folding line 88, and the folding line 101O is arranged to provide a closing strip for sealing the envelop after insertion of its contents, the respective sections 17 and 18 thereof, formed by the folding to be described, being adapted to provide an extra thickness of material at this part for a purpose which will presently appear.

Assuming the blank formed as described and various lines of fold clearly indicated the completed envelop is made up by the following operation. The side flaps 5 are folded inward on the line 77, then outward on the lines 1313, andfinally inward on the lines 12 -12, the extent of the side flaps being such that after the last folding operation one of said flaps will overlie the other, to permit of said contacting portion to be secured together, preferably by any of the usual substances employed for this purpose. As thus folded the side edges of the envelop are of quadruple thickness, and the connection between the face section and side flaps is of the accordion plait type to provide for an extension of the envelop to accommodate bulky articles. In this position of the parts the sections 14 of the lower sealing flap rest upon the section 15 thereof,- and said sections are folded upward on the line 1111 and secured against the outer surface of the side flaps 55. The respective side edges of the lower sealing flap is, of course, formed by the quadruple thickness of material incident to the folding of the side flaps along the lines 7-7, 1313 and 1212, so that the lower corners of the envelop are effectively reinforced against wear or breakage incident to the ordinary use. lVith the various sections of the envelop'secured in position as described a completed receptacle is provided in which the desired contents of the envelop are to be placed. In sealing the envelop against the escape of the contents the face section and superimposed side flap are folded upon the face section along the line 1010, the extension normally beyond said line being then oppositely folded upon the line 9-9, so that the section 18 of the blank rests against the face section 4, while the section 17 rests against the section 18. As the blank is folded down upon the face section along the line 8,the mouth of the envelop is efiectively closed. The folding of the blank as described to seal or close the envelop provides at the mouth thereof a quadruple thickness of material, as will be evident, and all of said sections, preferably at the points adjacent the side edges of the envelop are removably secured in sealing position through the medium of fasteners 19, as the usual or any preferred form of paper The fasteners 19 are preferably passed through the sealing section of the e11- velop at the points indicated, as at these particular points the envelop is of an increased number of plies owing to the folds of the side flaps along the lines 7, 131.3 and 12-12, as previously'described. The fasteners 19 are preferably inserted with their headed ends next the face side of the envelop, so that their securing prongs overlie the side flaps, as clearly shown in Fig. 2. In this condition of sealing the envelop is readily adapted for inspection by the postal authorities as required by law in certain classes of mail matter, though it is to be understood that, if de sired, the envelop may be utilized for first class mail matter by sealing the respective sections 1.7 and 18 in place, by any of the usual sealing mediums, or the securing prongs of the fasteners 19 may, if preferred, be protected by being covered with wax or a similar substance to receive an individual impression, whereby to guard the envelop against unauthorized opening without knowledge of the receiver. By preference the respective sections 17 and 18, and the face section of the blank are initially formed with openings 20 designed to respectively register when the blank is properly folded to provide for the ready insertion of the securing means 19.

The envelop when folded as described is a completed article, and it is to be noted that the address flap 6 extends from the closed end of the envelop free of all connection therewith except at the folding line 88. The address flap is designed to receive the address, and the stamp or stamps necessary for the transportation of the envelop. As the flap is free of the body of the envelop except as noted, the cancellation or other stamping to which the envelop is ordinarily subjected is applied to the address flap when extended, whereby to avoid affecting the contents of the envelop or the material thereof by stamping. In transportation, the address flap is, of course, designed to be folded onto the side flaps along the line 8-8, so that incidental separation of said flap from the body of the envelop is prevented.

In forming the envelop from the blank, as above described, it is to be understood, of course, that the textile fabric of the blank forms the inner face thereof during all the folding operation, so that in the completed article the receiving space of the envelop is lined with said fabric.

The envelop of this invention is formed of a single blank, the corners and sides thereof are effectively reinforced against wear, and the use of the blank made up of two plies of material provides a strong substantial envelop in which practically all mailable articles may be safely transferred.

Having thus described the invention what is claimed as new, is

1. A safety envelop comprising a face section, side flaps overlying the face section I and secured together, and a closing section formed by folding the upper portions of the side flaps and face section down upon the face section, and then folding back the upper portion of the face section and side flaps, there by disposing the aforesaid folds upon the face section, and means for securing'the folds of the closure in folded positions.

2. A safety envelop comprising a face sec tion, side flaps overlying the face section and secured together, the face section being extended beyond thefree edges of the side flaps, and a closing section formed by folding the upper portions of the side flaps and face section down upon the face section, then folding back the upper portion of the face section and side flaps, and finally folding rearwardly the extended face portion, thereby disposing the aforesaid folds upon the face section with the extended face portion overlying the side flaps, and removable means passed through all of said folds to secure the same to the face section.

3. A safety envelop comprising a face section, side flaps overlying the face section and secured to each other, and a closing section formed by folding the face section, and side flaps on a line transverse the envelop and adjacent to the u per end thereof, said fold resting upon the 'ace section, and then folding the face section and side flaps on a line parallel to the line of the first mentioned fold and adjacent thereto, said latter fold being bent to rest upon the side flaps, whereby the open end of the envelop is closed by a double fold resting upon the side flaps and comprising four thicknesses of material, and means for securing the folds of the closure in folded positions.

4. A safety envelop comprising a face section, side flaps overlying the face section, each of said side flaps being folded upon the face section by folding said flap along the line of juncture with said section, then folding the flap outwardly in alinement with the line of the first mentioned fold and then folding it inwardly to overlie the face section in alinement with the line of the second fold, said side flaps being secured to each other, and a closing section formed by folding the face section and side flaps on a line transverse the envelop and adjacent the upper end thereof, said fold resting upon the face section, and then folding the face section and side flaps on a line parallel to the line of the first mentioned fold and adjacent thereto, said latter fold being bent to rest upon the side flaps, whereby the open end of the envelop is closed by a double fold resting upon the side flaps and comprising four thicknesses of material, and means for securing the folds of the closure in folded positions.

5. A safety envelop comprising a face section, side flaps overlying the face section, each of said side flaps being folded upon the face section by folding said flap along the line of juncture with said section, then folding the flap outwardly in alinement with the line of the first mentioned fold and then folding it inwardly to overlie the face section in alinement with the line of the second fold, said side flaps being secured to each other, and a closing section formed by folding the face section and side flaps on a line transverse the envelop and adjacent the upper end thereof, said fold resting upon the face sec tion, and then folding the face section and side flaps on a line parallel to the line of the first mentioned fold and adjacent thereto, said latter fold being bent to rest upon the side flaps, the opposing end of the envelop being closed by folding the face section and overlying flaps in a line transverse the envelop and adjacent said end, the fold being toward and resting upon the side flaps, and

means for securing the folds of the closure in folded positions.

6. A safety envelop comprising a face section, side flaps overlying the face section and secured together, the face section being extended beyond the free edges of the side flaps, and a closing section formed by folding the upper portion of the side flaps and face section down upon the face section and then folding the face section and side flaps rearwardly upon the side flaps, the face section being folded rearwardly to provide an address fiap, thereby disposing the closing sec tion upon the side flaps with the extended portion of the face section overlying the side v flaps, and means for securing the folds of the closure in folded positions.

7. A safety envelop comprising a face section, side flaps overlying the face section and secured together, said side flaps being each folded upon itself at its juncture with the face section and disposed upon said face section to arrange the side flap folds wholly above said section, the face section being extended beyond the free edges of the side flaps, and a closing section formed by folding the upper portion of the side flaps and face section down upon the face section and then folding the face section and side flaps rearwardly upon the side flaps, thereby disposing the closing section upon the side flaps with the extended portion of the face section overlying the side flaps, and means for securing the folds of the closure in folded positions.

In testimony whereof, I affix my signature in presence of two witnesses.
